DaYi High-purity L-Glutamine uses raw materials from the Kyowa Group of Japan. Established in 1949, the Kyowa Group has over 70 years of expertise in pharmaceutical ingredients and food additive development. This L-glutamine is produced through a glucose fermentation process and is derived from non-GMO sources for enhanced safety. According to SGS testing, it achieves a purity level of 99.9%, with no additional additives or flavoring powders. It is one of the few truly “pure” L-glutamine products available in the Taiwan market, offering supportive nutritional benefits for post-operative care and recovery. Guided by the core philosophy of “removing intermediaries from health supplements,” the brand eliminates channel costs and endorsement fees, aiming to allow more patients and caregivers to access essential recovery nutrition at a more affordable price.
